Blessing in disguise you get to see any and all problems people encounter fo 2 months which gives you more time to make sure it was the right decision. I waited until now to actually place my order for that very reason if there are a lot of problems then I will cancel and wait some more. Want to get the most for my money.
I agree, waiting a bit longer to see reviews and see how people are reacting to either the Rift or Vive will be interesting to see, i have a feeling people will be delighted with either of these VR sets but like you i want the best value for money i can get.
I think one of the major considerations for everyone who orders either Rift or Vive to think about is after sales support and how efficient either company is at replacing parts/repairing sets that go faulty, i expect both sets will be very reliable but even with the best intention in the world inevitably a certain number of sets might experiance electronic failures or dead pixels in the case of the screens, people may accidentely scratch the lenses so i hope both companies will have a good stock of replacements.
I will want to know what the guarentee conditions are as well.
